Description
Technical field
The utility model relates to a kind of drier, specifically, relates to a kind of dry microwave fluid unit of solid particle that is used for.
Background technology
Microwave is a frequency at the frequency electromagnetic waves of 300MHz to 300GHz, and heating using microwave is high with its efficient, speed is fast, material is through characteristics such as self dielectric loss heatings, is widely used in fields such as food processing, dry materials, medicine sterilization and family cooking.On the function of heating, drying, sterilization, be different from traditional method with thermaltransmission mode heating, drying, sterilization.But there are deficiencies such as hot-spot in heating using microwave.
Fluidized bed drying is meant that drying medium makes solid particle under fluidized state, carry out dry process.The fluidized technology is widely used in the drying process process.Because material and drying medium contact area are big, the fierceness that material carries out in bed is stirred, so heat and mass is respond well, heat capacity coefficient is big.Uniformity of temperature profile in the fluid bed simultaneously, thus the hot-spot of product avoided.Device itself does not comprise mechanical moving element, and investment cost is cheap.Therefore fluidized drying is developed in recent years widely.Carry out drying but usually need to feed heating (greater than 80 ℃) gas, the one, temperature is too high, and cause can not dry heat-sensitive substance, and the 2nd, drying time is longer.
The utility model content
The purpose of the utility model is the deficiency that overcomes prior art, provides a kind of easy to operate simple, high efficiency, and rate of drying is fast, and can effectively improve the microwave fluid unit of pill quality.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of dry microwave fluid unit of solid particle that is used for comprises microwave drier, fluidized bed plant, air-blowing device and real time monitoring apparatus, and said fluidized bed plant is connected with the air-blowing device; Fluidized bed plant is located in the cavity of microwave drier, and real time monitoring apparatus is electrically connected with microwave drier and air-blowing device respectively; Said fluidized bed plant comprises fluid bed and gas distribution grid.Real time monitoring apparatus is realized the control to microwave drier and air-blowing device.
At the above-mentioned microwave fluid unit that is used for solid particle, the panel of said microwave drier is provided with touch-screen.
At the above-mentioned microwave fluid unit that is used for solid particle, said air-blowing device comprises air blast, relief valve, valve, airspeedometer.Air blast air velocity scope is 0 ~ 30m/s.
At the above-mentioned microwave fluid unit that is used for solid particle, be provided with some separated dishes in the said fluid bed, can carry out the multilayer drying, be polytetrafluoroethylene (PTFE) at a distance from the used material of dish.
At the above-mentioned microwave fluid unit that is used for solid particle, said real time monitoring apparatus comprises camera and computer.
At the above-mentioned microwave fluid unit that is used for solid particle, the top of said microwave drier and side all are equipped with the far infrared temperature probe.
At the above-mentioned microwave fluid unit that is used for solid particle, said gas distribution grid is provided with 35-42 purpose micropore.
At the above-mentioned microwave fluid unit that is used for solid particle, two magnetrons are equipped with in corresponding position, the left and right sides in the cavity of said microwave drier.
At the above-mentioned microwave fluid unit that is used for solid particle, the microwave power of said microwave drier is a stepless regulating, and power regulating range is 0 ~ 2000W.
At the above-mentioned microwave fluid unit that is used for solid particle, the stainless steel orifice plate that the place of distribution grid up and down of said fluid bed all has area to equate can prevent the leakage of microwave.
Compared with prior art, the utility model organically combines fluidized bed drying and microwave technology, combines advantage separately; The microwave fluid unit that provides has following beneficial effect: 1. firing rate is fast: because the effect of microwave compares with commonsense method, heat needn't be with heat conducting form from the surface to the material internal delivery; Directly with energy in whole material; In the inner instantaneous conversion of material is heat, has shortened heat time heating time greatly, and the non-conductor that a lot of material itself is a heat; Use common drying means, firing rate is slow.
2. be heated evenly: because the effect of fluid bed, material is suspended in the air, adds that material itself is also in continuous motion; Solid and gas two is fully contact mutually, and the material heating surface increases, and heat and mass is effective; Can accept microwave energy equably, thereby avoid hot-spot.
3. capacity usage ratio is high: microwave directly with the material interaction, need not add hot-air, large-area wall and conveying equipment etc., and heating clamber is the closed cavity of made, their microwave reflections make it outwards not reveal, and can only be absorbed by material.
4. the microwave fluid unit of the utility model is suitable for the drying in fields such as pharmacy, food, chemical industry, is particularly useful for the dried of the granule materials of low melting point, temperature-sensitive, easy oxidation.
